An Atlantic City teen already jailed on a gun charge is now accused of attempted murder in a daylight shooting that wounded a man and a woman.
A defaced handgun loaded with hollow-point ammunition was found, along with suspected crack cocaine, Sgt. Paul Aristizabal said at the time.
An investigation conducted by detectives of the Violent Crimes Unit has now linked him to the earlier shooting.
It was not clear if the gun he was arrested with was confirmed to be the one used in the shooting.
Cooper is charged with two counts each of attempted murder, aggravated assault with a deadly weapon and aggravated assault. He is additionally charged with conspiracy to commit murder, unlawful possession of a weapon and possession of a weapon for an unlawful purpose.
He remains in the Atlantic County Justice Facility.
